Leaded Glass

Our insulated leaded glass is custom made to order and can be made in two forms, Dual Face (recommended) or Thermal. Though Dual Face leading is limited to 3/8" wide lead and rectangular type patterns, it is covered by a longer warranty. The Dual Face leading projects to both the outside and the inside of the home for maximum visual effect. Thermal leading is available in 1/4" or 3/8" and will appear on both sides of one of the panes of glass. Options are endless with the Thermal leading but it will have a shorter warranty.
